Assessing land-use impacts on viability of intermountain trouts using Bayesian belief networks
Abstract
Many salmonid populations of the intermountain region of North America are threatened by habitat degradation resulting from changing land-use practices. Public lands managed by the USDA Forest Service and USDI Bureau of Land Management comprise a significant portion of the remaining suitable habitat. Public land-use decisions must consider the potential effects on sensitive species. A computer-aided viability assessment model is presented which can help anticipate impacts of management actions on resident trout populations. Central to this system is a Bayesian belief network that links physical habitat characteristics directly to reproduction and survival parameters of a population viability model. Recognizing that such linkages are imprecise and knowledge is uncertain, this system provides probabilistic risk assessments of land-use impacts. Preliminary results suggest that the principal threats to population viability arise from a combination of chronic habitat degradation and increased risks of major or catastrophic disturbances.
